_DISPLAY turns off the automatic display of the screen graphics (which is at around 30 fps) while displaying the screen graphics.


Syntax: _DISPLAY

  • Call _DISPLAY each time you want the screen graphics to be displayed if _DISPLAY was used previously.
  • Re-enable the automatic display by calling _AUTODISPLAY.


Example:

SCREEN 13, 0, 1, 0
dx = 1: dy = 1
DO
PCOPY 1,0
CLS
_LIMIT 60
x = x + dx: y = y + dy
IF x < 0 OR x > 320 THEN dx = -dx
IF y < 0 OR y > 200 THEN dy = -dy
CIRCLE (x, y), 10, 15
_DISPLAY
LOOP UNTIL INKEY$ = CHR$(27)


Returns:

Displays a circle going around the screen at 60 frames per second, displaying each frame to the screen.
